Miami dad Jean Carlos Aponte slashed throats of wife, 38, and son, 2, after admitting affairs to spouse who accused him of sleeping with Colombian escorts and telling her 'I broke ur trust,' cops say

A Miami father-of-two has been arrested for allegedly murdering his wife and son after admitting to having an affair before trying to kill himself, police said.

Jean Carlos Aponte, 40, has been charged with two counts of first-degree murder for the death of his 38-year-old wife Sara Ashley Gama and their two-year-old son Ethan Aponte.

Gama and her son were found dead inside the family's $850,000 home in Plantation, a city west of Fort Lauderdale in the South Florida metropolitan area on March 26 - the couple's four-month-old baby was found alive in a swinging chair when concerned relatives forced their way into the home.

According to an arrest affidavit viewed by DailyMail.com, the husband and wife had been messaging about their martial issues on the morning of the killings.

Gama sent a message around 6:50 a.m. that said: 'So let me ask you - when you went to Colombia for your dad's funeral what happened there? Because there are tons of escorts there.'

Aponte responded: 'I understand I broke ur trust.'

'You broke a lot of things. It's quite serious. You also broke our marriage vows,' Gama said.

'I'm not a good person,' Aponte replied.

'And you're realizing this just now as your come to Jesus moment,' Gama said.

The mother-of-two's search history revealed she had looked up 'just found out my husband cheated on me years ago' and 'how does alimony work in Florida,' according to the affidavit. She also visited a divorce lawyer's website shortly before the killing.

Court documents revealed video from cameras inside the house captured the couple arguing before the attack. 

A female voice is heard saying, 'because with your meetings and everything you cannot have full custody.' 

'So I hope those videos and everything that you got and all that stuff from the Super Bowl in Germany where she was skinny and all that you wanted. I hope she was worth it, don't come after my money, don't come after anything,' said the female voice.

'And we should have signed a prenup, we should have signed one.'

On March 26, Aponte failed to drop off the children at their grandparents' house, which prompted Gama's parents to go to their house and check on them, according to the affidavit.

They arrived at the house and heard the family's dog barking and the infant crying, which led them to believe something was wrong.

When they entered the home, they found their daughter lying on the kitchen floor in a bloodbath and Aponte unconscious on the floor of the master bedroom.

'Throughout the bedroom hallway dried red/brown blood prints could be seen, along with swipe or drag marks,' said the affidavit.

'On the kitchen counter next to [Gama] there were two kitchen knives resting on the cutting board and counter that were covered in blood.'

Autopsies found Gama had 28 stab wounds and her cause of death was determined to be sharp force injury.

Ethan's body was discovered in the pool and the autopsy determined he had four stab wounds. His cause of death was sharp force injury and drowning. 

Aponte was taken to the hospital, where medical staff said he appeared to have attempted to overdose on several of his prescription medications. 

Gama's father told police he was 'unaware of any marital issues' and 'knew them to have a happy marriage,' according to court documents.

Aponte's mother and sister told police he is a Marine veteran who was deployed in Iraq and was recently diagnosed with post-traumatic stress disorder.

Relatives also said he had a traumatic brain injury from a fight and suffered from depression. 

Aponte is being held at the Broward County Jail with no bond. He made his first court appearance on Sunday and was ordered to undergo a mental health screening, reported WTVJ.
